Thank you and congratulation for choosing the Felfil Evo Spooler.
Felfil Spooler is a plastic filament extruder, able to produce filaments for 3D printers starting
from industrial pellets or plastics wastes.
This guide is designed to allow you a good experience with Felfil Spooler, please read this
manual in all its parts before connecting and operating.
Felfil Spooler is suitable for domestic, research or business use; is wary of improper use.

Felfil Spooler.
Any kind of modification will be at your own risk, and will result in the decay of the warranty.
Felfil S.r.l. does not take any responsibility for damage occurred to people or object, caused by
such modifications or improper uses.
- Do not use vinyl and PVC, they will produce toxic emissions.
- Do not eat or inhale the filament.
- Do not use the machine if any parts are missing or damaged. If you notice any damage to the
unit, unplug the device immediately and contact the Felfil team for guidance.
Use the device only with specified input power. Using the device with any other input power is
likely to damage the electrical and/or electronic parts of the device.
Remind to keep the equipment out of children’s reach.
Use this device only to spool plastic filament for 3D printing. No other use has been tested.
- Do not insert your fingers in the moving parts.
- Do not throw water on the spooler.
- Do not hit the spooler and its accessories or you could damage the spooler.
- Please, never try to spool a plastic unless you are absolutely certain you know what type it is.
- Some polymers can undergo thermal decomposition resulting in potentially toxic fumes. So
always use the Felfil Spooler in a well ventilated area, or inprecence of a suction hood (not your
bedroom or inside your house), and understand the thermal decomposition properties of the
polymer you are extruding.
- Be sure to check in on it periodically.
The Felfil Spooler is a first-generation, experimental piece of hardware. Treat it as such.
Basically, use common sense.

Place Felfil Evo, Fan Array and Felfil Spooler on a table and arrange
them like in the pictures.
All the machines must be alligned: allign the Felfil Evo nozzle with
the filament support placed on the Fan Array and Felfil Spooler.
The filament has to be streight ahead, or the extrusion will result
compromised.

The first screenshot shows a calibration. During this step, you will see the distribution
reset. Indeed, every spooling session will start from the left side of the distribution.
Once the calibration is finished, a guided interface leads you to the spooling session.
Rotate the knob in order to switch settings and click it to confirm.
The first parameter that you can select is “Set Mode” which indicates the presets
used for the diameter control. Every mode is suitable for different materials.
Do not click anything during the calibration
process.
Tested with these materials:
ABS, HIPS
Tested with these materials:
PETG, TPU (2,85mm needed)
Tested with these materials:
PLA, Nylon
In Manual mode the diameter autocalibration is
disabled, it will operate at constant speed.
This mode is useful for sperimental materials.

The second parameter is the diameter you would like to obtain.
The sysytem will remember your last choice for the next extrusion.
Click to confirm.
This parameter is about the spool width. Measure it and set the distance.
Click to confirm.
If you are working in “Manual Mode” this parameter indicates the puller whells constant
speed (meter per minute). Adjust it according to your extrusion flow.
Felfil Spooler is ready to be used.
You can set it form a minimum of 0.5mm to a
maximum of 3mm.
This parameter is settable only in “Manual

Insert the filament through the proper supports placed on the fan array.
Insert the filament into the measuring system sliding up the little lever.
Once the filament is in position the puller wheels will start rotating.
!Use gloves to do this operation. The filament is still hot.
Do not stretch the filament, do this operation slowly.

Let the filament pass through the supports and between the puller wheels. Then guide it
in the distribution support.
Once the filament is pushed in the measuring system the puller wheels will start to rotat-
ing and the following information will appear. This is the main working interface of Felfil
Spooler.

The filament must pass under the empty spool. Let it go until the diameter will remain
quite constant. Then you can fix the filament to the spool.

Listed below there are all the parameters (menu items) that you can modify every time
you need during the extruding session.
Filament diameter desired.
From 0.5mm to 3mm
Preset for auto measuring and calibration.
See page 12 for more information.
Puller wheels constant speed. Adjust this parameter
according to your extrusion flow.
Available only in “Manual Mode”
Travel distribution width, modify this parameter
according to your spool width.
Travel distribution Speed. By default is set on
“auto” mode. This parameter can affect the filament
distribution.
Spool Speed. Modify this parameter if the spool
clutch is not working properly for your material, or if
your extrusion flow is over 1,5m/m
Fan Speed. You can modify the airflow of fan array if
necessary.

Usage
For a correct usage of Felfil Spooler please follow these suggestions:
- Place it on a flat and stable surface before operating (a table is quite good);
- Do not place anything near Felfil Spooler, it requires unrestricted airflow, for cooling,
proper operation and to protect the electronic components from overheating;
- Do not operate the machine for more than 4 hours. After that cycle, please could it down for
2 hours;
The first meters of filament will be inconsisten on diameter. Do not use this filament in your 3D
printer.
Felfil Spooler needs some occasional maintenance:
- Clean it regulary
- Be sure that every part can spin properly
- Use always gloves while working on still hot components.

Polymers Guide
In this section you can find some information about the plastics you can extrude with Felfil
System.
When using commercial pellets, rely on the maker’s identification of the type of plastic.
When using recycled plastic, check the markings on the item(s) to determine which type of
plastic you are using.
Do not mix types of plastic, as this may affect processing times, both in the extruder and in
the printer.
The following is a table of general processing temperatures. Notice that the processing tem-
perature may not be the same as the melt temperature.Temperatures will vary based on:
humidity, ambient temperature and chemical composition of the polymers.
NOTE: The temperature ranges in the chart are approximate. It will require some trial and error
to determine the right processing temperatures. Keep notes of actual temperature settings
with different types of plastics, along with other operational notes, to develop a procedure that
works well in your situation.
